A Valvetronix preamp incorporates a multi-stage tube amplification circuit to provide you with the distinctive distortion, response, and tonal characteristics of a classic tube amplifier. The result is a true-to-life reproduction of each model's characteristics. When Vox was designing the VT20X, they didn't just model the sound of guitar amplifiers, they employed VET (Virtual Elements Technology) to analyze each amp down to the component level.

A multi-stage Valvetronix tube preamp incorporates true tube circuitry, so you feel the subtle nuances that you'd expect from a tube guitar amp. Vox analyzed actual amp components and circuits when they designed the VT20X, so each of its 11 amplifier models sounds incredibly realistic. The modelling engine and FX are very similar to those on the Korg AX10G MFX (no surprise there) which does the same thing without the valve.The Vox VT20X modeling guitar combo amplifier employs sophisticated digital technology, along with a unique analog circuit, to bring you authentic tube power amp performance. The FX are not very special but do what is needed. I too also use manual mode almost exclusively, but you can store two things on the AD30VT and use it as you would a 2-channel amp with a diy f/s.ĭownside - too many knobs.& stock speaker (replace with Celestion G10-30 Greenback The valve is used in starved plate mode to help the chip model a valve amp, it is not a true part of the amplification chain, it is not a gain stage. The amp sounds best with this opened up almost but not quite to maximum, and use the master-volume to control the output level. The other 'hidden' control is the output level knob on the back. Obviously you can adjust noise gate level to kill any hiss, but the hiss is similar or better than a good valve amp's gentle buzz/hum. This turns the noise gate off and does introduce a little bit of hiss but gives much better string-touch sensitivity. Press bypass so no FX on, press and hold the 'tap' button whilst turning the 'edit 1' knob to zero. There is a 'hidden' control, the noise gate.
